Experimental infections enabled to test susceptibility of the goose and duck to M. avium. After intramuscular implantation of M. avium suspension, local lesions were observed at the spot of puncture in the geese, and miliary tuberculosis of spleen in 35 days, as well as miliary tuberculosis of liver after 69 days. In the ducks, local lesions were found at the spot of puncture in 35 days and miliary tuberculosis of liver and spleen in 69 days. Cultivation demonstrated mycobacteria in various tissues and organs since day 12 after infection. Peroral infection with contaminated feed caused lesions in spleen and intestine in the geese in 106 days, and then in liver and lungs in 133 days. The ducks had lesions in the intestine in 106 days, and in liver and spleen in 133 and 136 days, resp. Cultivation proved sporadic mycobacteria in liver, spleen, lungs and/or bone marrow and brain in both species. No tuberculous lesions were observed in the geese or ducks within 253 days of the experiment after infections by contacts with the TBC fowl. Cultivation demonstrated sporadic mycobacteria in liver, spleen, kidneys, lungs and bone marrow. The goose and the duck are very resistant to M. avium infection. The duck seems to be less susceptible ...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
